LP48 is a loop detector with improved functionality
controlling 4 loops and relay contacts.
LP48 is designed for industrial applications in
Eurocard standards. It is easily adapted to P. C. based
applications with RS-232 interface.

Applications

Vehicle counting for traffic lights

Vehicle detection in security line on roads

Vehicle speed calculation

Closed vehicle parking areas

Specifications

Adjustable relay hold time: You can set relay hold time after detection to 4 different values using 2 bit switches.

Adjustable Sensitivity: You can set the sensitivity to 4 different values using 2 bit switches. This feature allows you to detect/undetect less dense materials such as bicycle, motorbike etc

Isolation: The connection between the loop and the controller is isolated with a transformer. This isolation makes the system work more stable , safe and without any external interaction.

Displays: LP48 has 2 led indicators showing a) Fault: If loop is broken or deformed, is lit b) Activation: If a vehicle is detected is lit and stays lit until it goes away.

Function Keys (optional): The first 4 bit switches is used for function settings. The other 4 is used for frequency setting.

RS-232 interface: Without any need of another interface, you can directly connect the module to a P. C., and all monitoring is done by P. C. (only model LP48 has this feature.)

4 different modes.
(bits 1,2 of ….. switch on board)a-) 1on-2on Continuous hold: Output is activated when vehicle is detected and stays active until the vehicle leaves.
b-) 1on-2off Trigger on enter: Output is activated for 1 second when vehicle is detected. Another activation is possible only after vehicle leaves the loop.
c-) 1off-2on Trigger on Leaving: Output is activated for 1 second when vehicle leaves the loop.d-) 1off-2off 4 minute hold: Output is activated when vehicle is detected. Output stays active as long as vehicle is on the loop for a maximum time of 4 minutes. After 4 minutes the output is deactivated and the system is resetted. (If the vehicle moves but staying still on the loop, the output is activated for another 4 min.
